ENVELOP.

Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed February 9. 1907. Serial No. 356,635.

To all whom it may concern:

Be it known that 1, JOHN LORI), a citizen of the United States of America, residing at Fall River, in the county of Bristol and State of Massachusetts, have invented new and useful Improvements in Envelops, of which the following is a specification.

This invention relates to safety envelops, the principal object of the same being to provide reliable means to prevent the surreptitious opening of the envelop without indicating the fact that the seal has been broken by some unauthorized person.

Another object of the invention is to provide an envelop made from a single piece of paper, and in which the envelop, when closed, williorm an eflicient seal against surreptitious opening.

, These and other objects may be obtained by means of the construction illustrated in the accompanying drawings, in which:

Figure 1 is a plan view of the blank from which the envelop is formed, and the parts being shown in position before they are attached to complete the envelop. Fig. is a plan view of the address side of p the envelop. Fig. 3 is a central vertical section of the envelop.

Referring to the drawings for a more particular description of my invention, the numeral 1 designates the body portion of the envelop provided with an upper flap 2, and a lower flap 3. The upper flap 2 is provided with parallel slots 4, and an intermediate strap or band 5, while the lower flap 3 is provided with a reduced tab or connection 6 to which is integrally connected the address member 7 of the envelop. This address member is gummed entirely around its marginal edge, as at 8, upon its rear side. End flaps 9 and 10 extend from opposite ends of the body portion 1 of the envelop and said flaps are gummed, as at .11, upon their outer edges.

In assembling the envelop, the address member 7 is folded upon itself, and the flaps 2 and 3 are folded down against the body portion 1 of the envelop. The folded address member 7 is passed under the strap or band 5, and is then unfolded as shown in Fig. 1. The gummed portion 8 is then moistened and said address member is folded down and secured to the face of the flaps 2 and 3, the upper edge 12 of said address member being disposed below the upper edge 13 of the envelop. One of the flaps 9 or 10 is then inserted under the flaps 2 and 3 inside the envelop, and secured by its gummed portion 11 to the flaps 2 and 3. When the envelop is to be scaled the other flap is similarly fastened at the other end of the envelop. When the address is written upon the address mcm bcr 7, the postage stamp 14 is applied to the envelop, said stamp extending across the upper edge 12 of the address member and being secured also to the upper flap 2 of the envelop. In this condition it will be impossible to gain access to the interior of the envelop without breaking the stamp, or severing the lab 6, or otherwise mutilating the envelop.

An envelop made in accordance with my invention is comparatively simple in construction, can be manufactured at comparatively slight cost, and will effectually prevent surreptitious opening.

Having thus described the invention, what I claim is A safety envelop comprising upper and lower flaps, parallel slots formed in the upper Ilap, and an intermediate band or strap between said slots, an address member connected to the lower flap by a tab and passed through under the strap or band. said address member being gummed down to said upper and lower flap with its lower e( ge terminating below the upper edge of the envelop, and

end flaps gummed inside the envelop to said upper and lower flaps.

In testimony whereof, I affix my signature in presence of two witnesses.

JOHN LORD.
